To all whom it'may concern: I

Bait known that I, ALFRED STEWART, a citizen of 2 the United States,lresidin'g at i The same reference characters indicate the Sed'alia, inthe county of Doug as and State I same parts in all the views.

Let thenumeral 5 designate onevofthe ground wheels of the 'machine.ground wheel is not shownsince such illnstration is not necessary inorder to bring out the novel features or my improvements;

The numeral 6 designates the leftjdivider heard u )on which the conveyerchain 7 is of Colorado, have'invented certamnew and clear, and exactdescription'of the invention, suchas will enable others skilled in theart 5' to which it appertains to make and use the mounts The rightdivider boardS isd same, reference being had to the accompanyvoid of achain but upon it .is mountedan ing drawings, and to the figures ofreference l auxiliary board 9 to whichare secured a marked thereon,which form a part of this number of spring rods 10, whichnormaiiyspecification. I project into the space 12 between the two My inventionrelates to improvements in l divider boards, whereby thestalksof corncorn harvesters, my object being to do away as they pass betwee the twoboards, are with one of the top conveyerphains and one forced by thesprings 10, against the left of the lower conveyer chains of the machineconveyer chain 7 thus causing the one chain as heretofore constructed.In the placeof when aided by the tension springs ?.O, to the chainswhich are removed, I provide perform the function of the two chains aswhat I will term tension means which act heretofore constructed. Asshown in the upon the stalks of corn and press them drawing the upperextremity of the board against the conveyer chains on one side, 9 issupported by an upright bar 14 its upthus making the one chain in eachinstance per extremity being connected with the when used in cooperationwith the tension board by depending bolts 15. This board, means, performthe function of both chains however, may as the machine has beenheretofore conmanner. As shown in the drawing it forms structed. Asshown in the drawing in the a support for the tension springs 10. It isplace of the right top chain, I provide a evident that these springs maybe supported board equipped with a number of springs, in any suitablemanner. The right chain the same being secured to the said board atguard 18, is devoid of a chain. Its inner one extremity their oppositeextremities proedge, however, is reinforced as shown at 17, whereby thestalks of corn as they pass between the guards l6 and 18, are forced bythe member 17, against the conveyer chain 19, thus causing the one chaintoperform the function originally performed by two, thus greatlycheapening the construction of the machine. I

From the foregoing description the use and operation of the machine sofar as my improvements are concerned will be readily understood. Whenthe machine is in use, it is drawn by a team of horses and is inposition to straddle a row of corn, whereby the stalks are caused topass between the upper divider boards 7 and 8 nd the lower chain guards16 and 18.

Heretofore there have been two to con vcyer chains mounted upon theivider boards and two lower conveyer chains mounted upon the chainguards l6 and 18. The function of these chams, is to hold the corn inthe upright position during the cutting act; In myimprovement I do awe ywith one of the upper and one of the lower V'KlBZ' boards, whereby thestalks of corn are pressed against the left top chain. In the case ofthe lower chain, I reinforce the inner i edge of the right chain guard,whereby the stalks of corn are pressed inwardly against the left lowerchain thus making it perform the function ofthe two chains.

Having briefly outlined my improved con struction, I will proceed todescribe the same in detail reference being made to the accompanyingdrawing in which is illustrated an embodiment thereof. 5

In this drawing, Figure 1 a perspective view of a corn harvesterequipped with my improvements. in this view only one of the groundwheels is shown. Fig. 2 is a top plan view in detail of the zipper boardIn this view the eft conveyer chain and its operating devices areindicated in dotted lines. Fig.3 is a to view of the right lower chainguard whicii is indicated in dotted lines, the reinforced part, however,bcing shown in :ull iincs.

The other be supported in any suitable chains as heretofore explained,and as the stalks of corn are passed between the divider boards and thelower chain guards the springs 10 1n one instance and the rein orccment17 in the other instance, force the stalks oi. corn against the conveyerchains thus causing the one chain above and one chain below to performthe function heretofore performed by two;

' Having thus described my invention, What I claim is:

1. In a corn harvester, the combination with the top divider boards, anda conveyer chain mounted upon one'of the said boards,

a series of tension. elements mounted on they other board and eachprojecting between. the

twoboards and opposite the chain mounted on the other board, thesaid-elements being' of elements mounted on the other board and eachprojecting between the two boards and opposite the chain mounted on theother board, the said elements being-arranged one in front of anotherand serving to hold the stalks in operative relation with the con- Iveyer chain, substantially as described.

3. In a corn harvester, the combination with upper divider boards, lowerchain guards, a conveyor mounted on one. of the divider boards andanother conveyer mount-- ed on one of the chain guards, of a chainlessdivider board, a series of tension elements mounted on the chainlessdivider board and projecting into the space between the two boards, a.chainless lower guard, and an element mounted on the chainless lowerguard and projecting into the space between the two guards.

- in testimony whereof I aiiix my signature 1 in presence of twowitnesses.

' ALFRED STEWART.
